Abstract

A surgical instrument for dilatation and enlargement of the corpora cavernosa of the penis for use in surgical operations for the implantation of a penile prosthesis, the instrument having a mono-unit body of stainless steel and having two sectors including an operative sector and a handle sector, the operative sector having a substantially cylindrical configuration and being of considerable length with a slight curvature along its length forming a concave area on one side, the one side being smooth and slightly flattened, and a second side opposite the one side, the second side having ten longitudinal nerves arranged parallel to each other and in close proximity, and between which there are grooves which are also longitudinal, each of the nerves being provided with a longitudinal alignment of twelve uniformly distributed protuberances, each of the protuberances having a sawtooth shape including an oblique slanting planar surface which faces away from the handle sector, the end of the operative sector opposite to the handle sector being rounded, the operative sector of the body acting as a scraper, with the orientation of its protuberances facilitating penetration into the corpora cavernosa, and when pulled in the opposite direction out of the corpora cavernosa, carving furrows in the tissue of the corpora cavernosa.

Claims
